It’s not yet very known but a nice laid-back alternative to Perpignan’s festival:

It takes place in Brittany (Bretagne), in an old stone village, all the images are displayed outdoor in large format for 3 months. It kick starts today.
It is, indeed, a bit “french” oriented (I tried to find that translation button on the website, no luck), try to ignore that for the time-being :)
